Description

Technical Field

[0001] This utility model relates to the field of water pump technology, specifically to a submersible axial flow pump wellbore installation structure. Background Technology

[0002] Submersible axial flow pumps are commonly used in flood drainage applications due to their large flow rate, low head, easy installation, and low civil engineering costs. These pumps are typically used in conjunction with well casings. However, during pump operation, if the cable is not properly secured within the well casing, it often swings back and forth. Combined with the impact of water flow or debris, this can easily cause damage, leading to unit failure. Therefore, it is essential to invent a submersible axial flow pump well casing installation structure that is simple in structure, easy to install, and effectively protects the cable during pump operation.

A power cable and a signal cable are connected to the upper end of the submersible axial flow pump. A triangular lifting ring is installed at the upper end of the submersible axial flow pump, and an iron chain is connected to the triangular lifting ring. A support beam is installed above the cylinder body, and the upper end of the iron chain is connected to the support beam. The power cable and signal cable are fixed to the iron chain by cable ties. The upper ends of the power cable and signal cable pass through the cylinder cover. A power cable sealing assembly and a signal cable sealing assembly are respectively installed on the cylinder cover, and the power cable and signal cable pass through the power cable sealing assembly and the signal cable sealing assembly, respectively.

[0006] Furthermore, the chain has movable buckles at both ends. The movable buckle at one end of the chain is connected to a triangular lifting ring, and the movable buckle at the other end of the chain is connected to an installation ring. The installation ring is equipped with an installation stud, which is connected to the support beam via a nut.

[0007] Furthermore, brackets are provided on both sides of the inner cylinder, and the two ends of the supporting beam are connected to the brackets.

[0016] like Figures 1-3 As shown, a submersible axial flow pump wellbore installation structure includes a lower cylinder 1 and an upper cylinder 2 connected to each other. A cylinder cover 3 is installed on the top of the upper cylinder 2. A submersible axial flow pump 4 is installed inside the lower cylinder 1. A power cable 5 and a signal cable 6 are connected to the upper end of the submersible axial flow pump 4. A triangular lifting ring 7 is installed on the upper end of the submersible axial flow pump 4. An iron chain 8 is connected to the triangular lifting ring 7. A support beam 9 is installed above the upper cylinder 2. The upper end of the iron chain 8 is connected to the support beam 9. In this embodiment, a lower movable buckle 10 and an upper movable buckle 11 are respectively connected to both ends of the iron chain 8. The lower movable buckle 10 is connected to the triangular lifting ring 7. An installation lifting ring 12 is connected to the upper movable buckle 11. An installation stud is provided on the installation lifting ring 12. The installation stud is connected to the support beam 9 by a nut.

[0017] The power cable 5 and signal cable 6 are fixed to the iron chain 8 by cable ties 13. The cable ties 13 are used to bundle the power cable 5 and signal cable 6 at intervals of 300mm to 500mm. The upper ends of the power cable 5 and signal cable 6 pass through the tube cover 3. The tube cover 3 has a cable outlet hole.

[0018] During the installation of the submersible axial flow pump 4, first connect the lower cylinder 1 and the upper cylinder 2 and install them in the pump room mounting position. Then, use the lower movable buckle 10 to connect the triangular lifting ring 7 on the top of the submersible axial flow pump 4 to one end of the iron chain 8. Next, use cable ties 13 to tie the power cable 5 and the signal cable 6 together with the iron chain 8. Depending on the length of the cable in the well, control the spacing L of the cable ties 13 to be 300mm to 500mm. Then, screw the installation lifting ring 12 into the threaded hole in the middle of the support beam 9 for fixation. Then, use the upper movable buckle 11 to connect the other end of the iron chain 8 to the installation lifting ring 12. Finally, connect the submersible axial flow pump 4 and the connected power cable 5, signal cable 6, iron chain 8, and support beam 9 together. The components are hoisted together and installed in the well casing. Brackets 18 are provided on both sides of the upper casing 2.
